Subject: [PATCH] Vault: Explicitly default to 3DES CBC
|
|
|
483b06 |
|
|
|
483b06 |
The server-side plugin for IPA Vault relied on the fact that the default
|
|
|
483b06 |
oid for encryption algorithm is 3DES in CBC mode (DES-EDE3-CBC). Dogtag
|
|
|
483b06 |
10.4 has changed the default from 3DES to AES. Pass the correct
|
|
|
483b06 |
algorithm OID to KeyClient.archive_encrypted_data().
|
|
|
483b06 |
